WEBINAR:On-Demand

This program was inspired by httptest and another article I did, DNSWatch. In that article, I was looking for DNS names being looked up by browsers. In this program, I retrieve a Web page, display it, and list the hosts referenced in it. There are a lot of diferences in Web pages, especially in how to terminate a line and delineate embedded URLs. There are four main routines. GetHostAndPath is an interesting one. It uses the Uri class (uniform resource identifier) to break out the host and path. GetWebPage is the actual network code, copied from an example and slightly modified. There are several ways to do this send and receive; I just chose this one. GetHosts searches the retrieved page for hosts referenced in it. ChangeLfToCrLf is needed because of how different Web pages are terminated in various ways.
